All deleted Apps back on springboard 'waiting'-imageuploadedbymodmyi1361286265.191014.jpg

On my iPad 3, evasion iOS 6.1, a lot of times all of my already deleted AppStore apps reappear with a empty progress bar on the icons. After tapping some of them it disappears. After a some time this happened again. Does anyone know how this may come to be? Has anyone have the same problem? Does anyone here has a solution to this?
